HORSESHOE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 450,597, dated April 14, 1891.

Application filed August 23; 1890. Serial No. 362,3 iO. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN EDWIN BUcKLIN,

a citizen of the United States, residing at \Vashington, in the District of Columbia, have invented certain new and useful Improvements in Horseshoe-Machines; and I do hereby declare the following to be a full, clear, and exact description of t-heinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in horseshoe-machines; and it consists substantially in such features of arrangement, construction, and combinations of parts as will hereinafter be more particularly described and claimed.

The object of the invention, broadly stated, is to provide a horseshoe machine which shall at one operation effect the cutting of the blank and both the bending and 'swaging of the shoe, substantially as will hereinafter be more fully understood on reference to the accompanying drawings, in which- Figure 1 is a side elevation of a horseshoemachine embodying the features of my invention, and Fig. 2 is a vertical longitudinal sectional elevation taken on the line 90 x of Fig.

3. Fig. 3 is a front elevation of the machine with the oscillating or swinging anvil detached or broken off, so as to more clearly represent the construction and operation of the several parts. Fig. 4 is a side View in detail of a certain feature of the machine and which will be more fully explained hereinafter. Fig. 5 is a detail in perspective of the reciprocating guide-plate.

In carrying my invention into effect I provide a machine in the front of which is a plate or frame that is caused to reciprocate vertically between the two sides or walls of the machine, and this plate supports and carries with it both the cutter for the blank andthe bending or shaping rolls which bend the blank around the forming-die. This frame also supports at a line centrally intermediate of the shaping-rolls a vertical tube or sleeve which is slotted diametrically for a suitable distance from its lower end, and a spiral spring is contained in said sleeve, against the action of which at proper intervals a movable finger is caused to be held down over the forming-die,

so as to accurately center the out blank and permit the shaping-rolls to properly eifect the shaping of the shoe. The said movable finger works in the slotted end of the tube,

and the arrangement thereof is such with respect to the connection between the vertically-reciprocating plate and the operatingshaft of the machine, that immediately the blank is out the said finger is brought into position for holding said blank. As soon as the shaping-rolls effect the bending of the blank around the forming-die the vertically reciprocating plate or frame which carries such rolls begins to re'cede upwardly, and at this time a pivoted oscillating or swinging anvil begins to move inwardly toward the forming-die. This swinging anvil carries the swage which presses the shoe into form, the

said shoe being both creased and pressed into proper configuration by its action. Just at the time the swage reaches the forming-die the finger, which has been held down upon the blank, will be lifted by virtue of the vertically-reciprocating plate having receded upwardly to its utmost limit, and at this time also the forming-rolls will have been restored to their former positions, ready to again be carried down on the next 'movement of the reciprocating plate.

Beneath the shaping-rolls and the cutter for the blank, and in a plane coincident with the plane in which the reciprocating plate or frame moves, is a guide-plate for receiving and holding the bar from which the blank is cut, which guide-plate is also made to reciprocate vertically, so as to be carried downward immediately the blank is cut from the bar? thus enabling the reciprocating plate or frame to move downward with the shapingrolls for bending the blank around the forming-die.

The cutter for the blankhas a stop opposite to it, and both the cutter and stop are taken or received into slots in the upper edge of the guide-plate as the reciprocating frame moves downward, and it is in this way that the said guide-plate is operated. the downward move ment of the latter taking place a little after the frame has started and immediately the ice blank is cut from the bar. The upper or return movement of the guide-plate is effected through the action of a spring simultaneously with the upward or return movement. of the plate or frame.

During the severance of the blank from the bar it is of course necessary that the guide which holdsthe bar shall be sustained against the force necessary to effect the cutting; and it is further necessary, from the construction resorted to, that as soon as the blank has been cut the guide shall be carried down out of the way of the forming-rolls. To provide for this I employ a stationary slotted tube extending upwardly from the base of the machine and containing a spiral spring, and working in this tube againstthe action of the spring is a sleeve which tits around a rod pendent from the guide-plate on one side at its lower portion. This sleeve is adapted to turn or rotate on the rod, and is formed with a nose or projection which ormally rests upon the upper edge of the stationary tube just to one side of the slot thereof. In this position of the parts the guide-plate will be sustained in position to enable the cutter to do its work; and then immediately the blank has been cut there will be a lever actuated from the drive-shaft of the machine to move against the nose or projection on the sleeve, and thereby turn the sleeve and bring such nose or projection into the slotof the tube in which the sleeve works. At this time the guideplate commences to move downward with the ing and swaging of the shoe has been completed the parts will all be restored as originally. When the nose of the sleeve again reaches the upper edge of the slotted tube, it is forced over to one side of the slot by a spring-actuated pin which works against the same.

Reference being had to the several parts of the drawings by the letters marked thereon, A A represent the two sides or walls of the machine, in which the main drivingshaft B has its bearing, as shown. The said shaft is provided centrally between the two walls or sides with an eccentric C, which ismovably connected to one end of a walking-beam D, that is supported by a standard E, the other end of said walking-beam being in movable connection with a link F, which in turn is in movable connection with the'vertically-reeiprocating plate or frame G, which works on guides CLCL, bolted or seen red to the front edges of the walls or sides A A at their upper portions. Thesaid vertically-rcciprocating frame or plate is formed or provided at its lower 1 portion with hollow sleeves or guides Z) Z), oppositely arranged to each other, and in these guides are located or arranged the horizontal blocks or carriers 0 c, in which the shaping or bending rolls (Z (Z have their hearing, as shown.

Secured to theinner edges of the opening Z in the vertically-reelprocating plate are the Hat springs d d, which extend down behind the shaping-rolls and bear outwardly against reciprocating frame,and as soon as the bendthe blocks or carriers with the tendency of forcing them outward or apart. The outer ends of these blocks or carriers work against the inclined faces of the guides e e, and when the reciprocating plate or frame G moves downwardly it will be apparent that the sliding blocks or carriers will be forced together inwardly and the bending-rolls caused to work around the outer surface of the forming-dle H with powerfuleffect. On the return or upward movement of said plate or frame the sliding carriers cl d will again be forced outward, together with the rolls.

'lhe forming-die H is made integral with a plate I firmly set in the machine and backed or re-enforced by abrace J, secured between the two sides or walls A A, so as to furnish enough resistance to the action of the swage. One of the sleeves or guides b is formed or provided with a cntterf for the blank, and the other is formed or provided with a stop g, against which the end of the bar from which the blank is cut abuts, and after the initial downward movement of the vertically-reciprocating plate or frame G, at which the blank is out. the said cutter and stops by the contin ued downward movement of said plate enter notches 1 ll, formed in the upper edge of the guide-plate, and thus is said plate forced downward. The said guide-plate is formed or provided at its lower portion with a rod 71, which works in a tube j, against the action of a spiral spring 7;, contained in said tube, and after the plate has gone downward the extent of its limit it will be again forced upward by the springsimultaneousw th the upward movement of the reciprocating frame or plate G.

The heated bar from which the blank 18 out is supposed to be fed to the maci nnefrom the side (left-hand side in the drawings) and in line with the guiding-spaces m m of the guide-plate, which spaces are formedby tu rning over the side edges of the plate. thee h 1g. 5 for a more complete understanding.) these spaces receive the end of the bar as it 1s 1nsorted.

in order to sustain the guide-plate from downward movement until after the blank has been cut, I provide a stationary tube 0, extending upwardly from the base M of the machine, the said tube being open at its upper end and slotted, as atn, for asuitable distance from said upper end. (See Fig. a.) In this tube is contained a spiral spring 0, and working downward in the tube against the action of the spring is a sleeve 1'), which fits upon a rod or pin q pendent from the lower portion of the guide-plate at one side, and s adapted to turn on said rod or pin. This sleeve is provided with a nose or pro ection 7', which rests upon the upper edge of the slotted tube when the guide-plate is up, thus firmly sustaining the plate while a blank is being cut from the bar. Immediately the blank is out a bent arm or lever P will beactuated by a cam 5 (see Fig. 2) on the driveshaft to move forward, so that its lower end will come in contact with the nose 4' and thereby turn the sleeve 19 around on the rod q until said nose is carried into the slot 'n, whereupon the rod and sleeve will be carried down into the tube by descent of the guideplate. As the guide-plate is again caused to recede upwardly, the spring 0 will at the same t me reactand the nose or projection be again li fted over the upper edge of the slotted thbe.

lhe lever P, in pushing against the nose 0', does so against the action of a spring-bolt 25, that works in a sleeve to, supported by a bracket c, that is secured to the lower portion of the guide-plate, as shown in Fig. 4. The said bracket is formed integral with and at right angles to a slotted guide to, which moves on a pin or screw as, and which serves to maintain the relative positions of the parts. It is this spring-bolt which serves to again force the nose 0' over onto the upper edge of the tube 0 after said nose has been raised above the upper extremity of the slot at. The upperportion 2 of the lever P works through a stat onary guide 3, and the rear end of said lever is formed or provided with a nut or head 4, between which guide and head is arranged a spiral spring 5, surrounding the lever, which SPI'lllg becomes compressed when the lever is urged forward by the cam on the drive-shaft, and then after the cam has passed and the lever has effected its function by working aga nst the nose 1' on the sleeve the said spring expands and causes the return of the lever in an obvious manner.

. R representsa tube that is screwed or bolted to the face of the vertically-reciprocating plate centrally thereof, the said tube being slotted diametrically for a suitable distance from its lower end, as shown at y, so as to receive and accommodate the movement of a branch 2 of pendent finger 7, the said finger acting to move down upon the blank immediately it has been cut from the bar, and to hold such blank upon the forming-die until after the shaping-rolls have efiected the bendmg. As the reciprocating plate or frame descends, the slotted tube moves down upon the branch 2' of finger 7, and such finger remains restin g upon the blank over the top of the forming-die until the reciprocating plate again ascends, whereupon the said finger is lifted by the bottom of the tube. The lifting of the finger takes place just at the time the swinging anvil S has carried its swage 8 up to shape or crlmp the shoe. This swinging anvil has its bearings between the two sidesA A at the forward end of the machine, as shown,and is operated to move forward to ward the formlng-die at the proper intervals through the medium of eccentrics 9 9 on opposite sides of the machine and their connecting arms or rods 10 10.

Located in suitable position in front of the machine at its forward end is a curved discharge-chute V onto which the shoes fall, and

from which they are discharged as fast as they are turned out from the machine.

It is thought that from the foregoing description the construction, arrangement, and operation of myinvention will be thoroughly understood; but. it may be added that no second heating of a blank is ever required in making a shoe from this machine, and further stated that the several parts are so arranged that the cutting, bending, and swaging of the shoe is effected in rapid succession by a single operation of the machine, or, in other words, by a single revolution of thedriving-shaft.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
